Cómo se puede cambiar una bañera por un plato de ducha

How can a bathtub be replaced with a shower tray?

You have probably found yourself more than once standing in front of your bathroom mirror, imagining how to gain a few extra feet in a room that sometimes feels a little cramped. 

The decision to remove the bathtub and install a shower usually stems from the search for comfort, but it ends up becoming one of the best investments you can make in your daily well-being. 

It is no longer just a matter of aesthetics or following trends in bathrooms; above all, it is a way to adapt your home to your current pace of life, gaining agility and well-being, gaining agility and transforming a space that once felt somewhat cumbersome into a much calmer, more fluid and open corner.

The change your bathroom and quality of life need

We often get used to obstacles at home without realizing how much they restrict our movements.

The bathtub that once served its purpose may now represent a visual and physical barrier that takes away from the dynamism of your mornings. 

When researching how to replace a bathtub with a shower tray, you discover that the process is much simpler than it seems and that the impact on your routine is immediate. 

You will gain a sense of freedom of movement that you did not have before, while also eliminating the unnecessary effort of stepping over a high edge every time you need to freshen up. 

Direct benefits of renewing your space

When you decide to take the step, the benefits begin to appear even before the work is finished. These are the reasons why this small renovation makes so much sense:

  • Safety for everyone: The peace of mind of stepping into the shower without fear of slipping or making a wrong move is priceless. A level, slip-resistant floor provides the confidence that both you and your loved ones will appreciate over the years.
  • A more spacious appearance: By clearing the volume occupied by the bathtub, the bathroom can breathe. Light travels better and the space seems to multiply, which is especially valuable if your bathroom does not have many square meters.
  • A breath of fresh air for the planet: We are all more aware of the importance of conserving water. An efficient shower lets you enjoy your time washing while drastically reducing consumption, which shows both in your commitment to the environment and in your monthly bills.
  • Cleaning without complications: Modern materials are designed to repel dirt and prevent limescale buildup, saving you time and effort when maintaining your home.

A smart investment in your home

It’s only natural for one of your first questions to be how much it costs to replace a bathtub with a shower, but I encourage you to also consider it from the perspective of profitability. 

This renovation not only gives you greater comfort now; it also increases your property's real value. 

A bathroom with a modern, clean, and accessible shower is one of the details that most influences how a home is perceived, making it much more attractive and functional for any future valuation.

Preliminary planning: what you need to know before getting started

Before removing the first tile, visualize the result and anticipate the technical details that will ensure lasting success. 

When considering how to replace a bathtub with a shower tray, precise measurements and the choice of suitable materials will be the foundations for preventing dampness and creating a safe, renewed space.

Measurements and proportions to make the most of every corner

The logical first step is to measure the space your current bathtub will leave. In general, these pieces are usually between 140 and 170 centimeters long, giving you a very interesting range of possibilities for planning the new layout.

  • Custom shower trays: if the space has irregular dimensions or you want the shower to span the entire wall-to-wall width, mineral-filled shower trays can be cut with millimeter precision so they fit perfectly.
  • Width optimization: although standard bathtubs are usually about 70 centimeters wide, you can take advantage of the work to gain a little more space if the passage area allows it, thereby improving your comfort inside.
  • The subtlety of thickness: ultra-thin shower trays are favorites today because they allow an almost floor-level entrance, eliminating steps and creating a very elegant visual continuity.

The materials that will define your experience

Choosing the material is not just a matter of budget, but also of feel and durability. Depending on what you are looking for in your home, there are options that can completely transform the atmosphere.

Resins and mineral filler

They are the most sought-after option when replacing a bathtub with a shower because of their excellent balance between design and durability. They are made from a mixture of resins and marble, finished with a coating that makes them antibacterial and very safe to walk on. 

Their warm feel and the option to choose textures that imitate stone or slate make them a very versatile and welcoming solution.

Ceramic and acrylic

Ceramic is the traditional material: it withstands even the strongest cleaning products remarkably well and does not scratch easily, although it tends to feel colder to the touch. 

On the other hand, acrylic shower trays are lightweight and withstand impacts well, offering a smooth surface that suits any decorative style.

The hidden importance of the drain and slope

A detail that is sometimes overlooked when calculating the cost of replacing a bathtub with a shower is everything hidden beneath the surface. The drain valve must have sufficient capacity to remove water quickly, preventing it from accumulating while you relax.

Similarly, the slope toward the drain must be perfectly executed. If the base supporting the new shower tray is not properly level, water could stagnate in the corners, eventually causing damp stains or hygiene problems. 

Ensuring that the connection to your home’s pipes is watertight is the final step in making your new shower not only attractive but also fully functional and worry-free.

How much does it cost to replace a bathtub with a shower in 2026

Addressing the financial aspect is probably the step that raises the most questions before giving the renovation your final approval. 

Understanding the cost of this transformation requires looking beyond a fixed figure, since it involves various line items ranging from the initial removal of rubble to the final finishes of the taps and shower screen. 

Nowadays, the market offers solutions to suit a wide range of budgets. This makes the decision to replace a bathtub with a shower accessible, whether you are looking for a quick, functional update or prefer a high-end renovation with designer materials and advanced technology.

Breakdown of the main renovation costs

To give you a realistic view of the expense, it is useful to divide the investment into three main sections that usually appear in any professional estimate. 

This distinction will help you understand where every dollar is invested and why prices vary depending on the quality of execution you choose.

  • Specialist labor: This includes the masonry work required to remove the tiles and rubble, as well as the plumber’s work to adapt the water connections and the new drain point.
  • The shower tray and wall covering: The price varies significantly depending on whether you prefer ceramic, acrylic, or mineral stone. You must also add the cost of the tiles or technical panels needed to cover the space previously occupied by the bathtub.
  • The shower screen and taps: They are the finishing elements and those that have the greatest impact on your daily well-being. A tempered glass shower screen with limescale-resistant treatment is an investment that will make subsequent cleaning much easier.

Factors affecting the final budget

Every bathroom has its own characteristics that can change the final cost. When planning how to replace a bathtub with a shower tray, consider whether the age of the pipes means the plumbing should be renewed to prevent leaks. 

Factors such as the property's location, debris removal, or moving the water connections to install a hydrotherapy column will also affect the budget.

Price comparison by quality level

As a general guide, you can place the required investment into three price brackets to help you decide what best fits your plans.

Essential range

This option is ideal if you are looking for a practical, affordable solution without complications. It usually uses acrylic shower trays and standard-profile screens with thinner glass. 

Prices generally range from 850 to 1,250 euros, covering basic work with durable, straightforward materials.

Balanced range

This is the option I most recommend when considering how much it costs to replace a bathtub with a shower from a long-term perspective. 

This range includes ultra-thin mineral-cast shower trays with a warm feel, 6-millimeter safety glass screens, and highly durable wall coverings. The cost is usually between 1,350 and 1,950 euros.

Designer or premium range

If you are looking for a complete aesthetic transformation, this is the option for you. It includes flush-mounted shower trays with almost invisible linear drains and large-format fixed screens made with extra-thick safety glass. 

This type of work can cost over 2,300 euros, depending on the exclusivity of the finishes and the complexity of the work beneath the floor.

Step by step: how to successfully replace a bathtub with a shower tray

Understanding the technical process involved in your bathroom will give you the peace of mind you need before the work begins. 

Although the work is usually quick and generally completed within twenty-four to forty-eight hours, it requires a logical sequence of steps carried out with complete precision. 

Knowing exactly what to expect at each stage will allow you to follow the progress of the work and understand the value of every construction detail. 

When planning how to replace a bathtub with a shower tray, coordination between the masonry and plumbing work becomes the critical factor in ensuring that the result is both attractive and functional.

Preparing the space and protecting your home

Before generating even the slightest amount of waste, the technical team must protect walkways and those bathroom elements that will not be replaced. 

It is common to cover the floor from the entrance of your home to the bathroom with cardboard or protective felt to prevent any damage from the movement of materials. 

Similarly, the sink and toilet are usually protected with plastic sheeting, preventing fine demolition dust from affecting their finishes or entering the flush mechanisms.

Demolition and debris removal: the bathtub removal process

This is the noisiest phase, but also the one completed most quickly. The old faucets and shower screen are removed, after which the tiled section surrounding the bathtub is chiseled away.

  • Removal of the bathtub: depending on whether your bathtub is made of enameled steel, cast iron or acrylic, it is carefully removed to avoid compromising the adjacent walls.
  • Clearing the space: once removed, all the old bedding material, such as sand or brick remnants, is taken out until the floor and walls are completely exposed.
  • Waste management: all debris must be placed in rubble sacks and taken to an authorized recycling center, always complying with environmental regulations.

Plumbing adjustments and floor leveling

Once the space is clear, it is time to work on the plumbing. The hot and cold water connections are adjusted to the height of your new faucets and, most importantly, the drain is positioned. 

When removing the bathtub and installing a shower, the drainage point usually changes location, so it is necessary to install a new shower drain with a high-flow valve that connects perfectly to the main drainpipe. 

After this, a level mortar base is created on which the tray will rest, ensuring firm support across its entire surface to prevent the material from developing stress or cracks in the future.

Shower tray installation and watertight sealing

The shower tray is placed on the mortar base, checking that it is perfectly level. Once secured, the joints are sealed, an area where it is not advisable to compromise on quality. 

Using neutral, fungicidal or high-strength polymer sealants will prevent water from seeping into the walls. 

If you are concerned about how much it costs to replace a bathtub with a shower, remember that part of that investment specifically ensures that these sealing materials are long-lasting, helping you avoid damp problems with the neighbors downstairs.

Wall coverings and final finishes

The gap in wall covering the area left exposed after removing the bathtub must be covered to ensure complete waterproofing. You have several popular options that will define the style of your new bathroom:

  • Traditional tiling: new tiles are installed, either to create a decorative contrast or to maintain continuity with the rest of the room.
  • Composite or resin panels: they are large-format pieces made of the same material as the shower tray, allowing the area to be covered with almost no joints and providing superior hygiene.
  • Microcement: a modern, seamless alternative that adds a contemporary feel and eliminates visual divisions.

Finally, the shower screen and new shower column are installed, followed by a watertightness test to confirm that the water flows correctly toward the drain and that there are no leaks before the renovation is considered complete.

Materials and trends for a professional finish

Choosing the final finishes combines aesthetics and functionality to define your bathroom’s personality. 

When considering how to replace a bathtub with a shower tray, prioritize materials that ensure durability and make cleaning easier. 

Choosing the right components will transform a functional renovation into a refuge with a cutting-edge, welcoming, and durable design.

Faucets: efficiency and pleasure under the water

The faucet is the heart of your shower, and your choice affects both how you feel and your household resource consumption. 

There are options that dominate modern installations and can completely change your experience every morning:

  • Thermostatic faucet: it allows you to select the exact water temperature and keep it constant, even when other taps in the house are turned on. It is the safest option for avoiding sudden temperature changes and the most efficient if you want to save energy.
  • Single-lever faucet: it is the classic, simple, and reliable solution. Although it is usually somewhat cheaper, it requires a small manual adjustment each time you use it to find the ideal temperature.
  • Hydromassage columns and large-format showerheads: if space allows, these options add a rain effect that elevates washing to a superior wellness experience, helping you disconnect from daily stress.

Shower screens: the invisible barrier that adds elegance

The shower screen ensures that the water stays where it should and also defines the room’s sense of spaciousness. 

When calculating how much it costs to replace a bathtub with a shower, it is highly recommended that you invest in high-quality glass to avoid having to replace it prematurely.

Tempered glass and thickness

The current safety standard uses tempered glass between 6 and 8 millimeters thick. These panes are designed so that, in the unlikely event of breakage, they fragment into tiny pieces that do not cut, thereby protecting the whole family.

Limescale protection treatment

This finish has become almost essential. It is an invisible coating that seals the pores in the glass, allowing drops to slide off easily. 

As a result, limescale and soap residue do not become embedded, keeping your glass shower screen transparent and shiny with much less effort on your part.

Wall coverings that transform your walls

One of the biggest challenges when removing a bathtub and installing a shower is deciding how to cover the section of wall that was previously hidden. Current trends avoid visible patchwork and seek a fully integrated, harmonious look.

  • Composite panels: they are installed directly over your old tile, so you avoid creating more rubble on the walls. They are made in the same colors and textures as the shower tray, creating a very elegant visual continuity.
  • Large-format ceramic tiles: large-format rectangular pieces reduce the number of grout joints. This not only gives your bathroom a more modern feel, but also makes the space more hygienic by minimizing the points where mold tends to accumulate.
  • Transition profiles: if you decide to keep part of the original tile, aluminum or stainless steel profiles will help you create a clean, professional transition between the old material and the new finish.

Common mistakes to avoid when removing your bathtub

Taking on this type of renovation requires a vision that goes beyond purely aesthetic considerations. Only then can you avoid those structural failures that tend to become apparent when the work already seems finished and the team has left. 

Often, the rush to see the renovated bathroom or the temptation to choose the lowest quote can lead you to make mistakes that compromise the durability of the entire installation. 

When considering how to replace a bathtub with a shower tray, it is vital to pay attention to what happens beneath the tiles and inside the walls. 

An oversight in planning or careless technical work not only ruins the experience of having a brand-new bathroom, but can also lead to costly repairs and unnecessary problems with neighbors due to accidental leaks.

Ignoring the condition of old pipes

This is the most frequent failure and the one that causes the most headaches in the medium term. When removing the bathtub, the lead or old copper pipes are left fully exposed, and that is when you must make a sensible decision.

  • Material fragility: if your home is several decades old, the connections may have been weakened by corrosion or accumulated limescale. Taking advantage of the open access to replace the flexible connectors and drain elbows is one of the wisest decisions you can make.
  • Existing blockages: not checking whether the main drain flows properly before installing the new shower tray is an unnecessary risk. Preventive cleaning of the drainage pipe will ensure that water does not back up once everything has been sealed.
  • Diameter compatibility: ensuring that the new drain valve fits the original pipe without forcing it is the only guarantee of maintaining the system's complete watertightness over the years.

Not allowing enough space for the shower screen to open

Your bathroom's functionality depends entirely on how you move around it once the shower has been installed. 

When calculating how much it costs to replace a bathtub with a shower, people sometimes choose the shower screen based on its price or design, forgetting the room's actual layout.

  • Physical obstacles: it is very common to install a hinged shower screen that, when opened, hits the toilet or the sink unit. In smaller bathrooms, sliding doors or fixed panels are usually much smarter and more convenient options.
  • Genuine accessibility: if the reason for your change is to improve safety, the entryway must be wide enough. An opening that is too narrow cancels out the benefits of removing the bathtub, making access more difficult and reducing the comfort you wanted from the outset.

Failures in waterproofing the joints

Water is persistent and takes advantage of any pore to seep where it should not. Applying a layer of silicone to the exterior joints is not enough; true protection lies in the shower tray base and in preparing the walls.

The importance of the waterproofing strip

Sometimes waterproofing strips between the shower tray and the wall are omitted. Without this reinforcement, the seal depends exclusively on silicone, a material that deteriorates over time and with the use of cleaning products. 

If the seal fails, moisture will inevitably penetrate the partition wall.

Insufficient or incorrect slope

Although modern shower trays already have a built-in slope for water drainage, if the mortar base supporting them is not perfectly level, water may end up pooling. 

This not only creates unsightly mold stains, but also increases the risk of slipping and causes materials to deteriorate prematurely.

Neglecting bathroom ventilation

When switching from a bathtub to a shower, it is usually used more frequently, and steam generation is much more concentrated. 

If your bathroom does not have adequate ventilation, whether a window or a powerful extractor fan, condensation will eventually affect the ceiling paint and the grout between your new tiles. 

This is the ideal time to check whether your ventilation system is sufficient for the new volume of moisture you are going to generate.
