We tell you about the advantages of walk-in showers, and how to overcome any possible technical drawbacks in their planning and installation.

Floor-level showers (or walk-in showers) are synonymous with comfort, safety and spaciousness. Originally used in the baths of Ancient Rome, they provide a host of advantages, both aesthetic and functional, by reducing bathroom elements to a minimum.

The extra-flat shower trays are the most efficient alternative when it comes to creating a walk-in shower.

  1. Bathrooms become easier to clean and maintain.
  2. The floor is continuous, so this elimination of architectural barriers offers a level of safety unmatched by other systems.
  3. They facilitate open spaces and clear environments of their clutter. The visual range they provide gives the bathroom a minimalist and purified image.
  4. No building work is required and they are cheaper than normal shower trays.
  5. At mcbath, extra-flat shower trays are available in a multitude of formats, textures or colours, even custom-made to order for maximum adaptability.

Walk-in shower trays: possible drawbacks and how to avoid them

However, despite their many advantages, we must take into account certain technical peculiarities when designing and installing floor-level shower trays.

  1. The shower should not be left fully open, even if solutions are used to make it look that way. Incorporating a tempered glass sheet in one part of the shower will help to close the space off and prevent water from escaping.
  2. Its design must take into account the location of the taps, such as the hand shower and the sprinkler, and in order to avoid leaks, the path the water takes.
  3. Our shower trays are designed with the exact inclination needed to evacuate water. However, depending on the design of the bathroom and shower itself, it may be worthwhile adding a slight slope towards the drain, as long as the characteristics of the project and the floor allow it and it is advised by our technician. It is recommended that the average gradient of this slope is about 6 or 7 mm.

Preventing water from leaking out of the shower tray

Although there is always a risk of water leaking out of an extra-flat shower tray, with professional advice and impeccable installation, and if the instructions in the previous point are followed, you will be ensured a safe installation with clean water evacuation and no leaks.

The reasons why water may overflow and run out of the shower tray at floor level are usually:

  • A poorly installed shower screen: there may be gaps between the silicone and the screen that cause water leakage.
  • Water valve: sometimes the valve does not have the capacity to absorb all the water due to blockages, causing water to accumulate and possibly run out of the shower tray.
  • Poor installation in the shower tray: the floor-level shower tray must be level to prevent water from stagnating or running out.


In the following section we tell you how to install a floor-level shower tray effectively to avoid problems with water leaks.

How to fit a floor-level shower tray

STEP 1: Turn off the main water supply

Water should be shut off to prevent leaks.

STEP 2: Handle equipment with care

When installing a shower tray flush with the floor, it is essential to avoid any damage to the shower tray.

STEP 3: Measure the surface where the shower tray is to be installed

It is essential to know how much space the shower tray and screen will take up. It is necessary to make sure that the installation is going to be carried out with a product that is suitable for the available space.

STEP 4: Drainage

It is important to mark the location of the drain on the surface where the floor-level shower tray is to be installed.

STEP 5: Place the shower tray drain flush with the floor so that it will fit

For floor-level installation, make sure that the drainage area is positioned at the right height, and check that the pipe will have a 2% drop to the drain.

STEP 6: Level the floor

Once step 5 is complete, prepare a levelled mortar or cement bed to prevent warping or water loss. 

STEP 7: Check for water leaks

The shower tray should be installed and the floor should be checked to ensure that it is level and that there are no water leaks.

STEP 8: Connecting the drain

Fit the valve ring and tighten with screws.

STEP 9: Covering the wall with a shower panel

Shower panels allow us to extend the finish of the shower tray onto the wall, providing continuity and design to the shower.
