When we advise against a walk-in shower

When the floor is too shallow

A walk-in shower needs space under the finished floor for a trap and a waste pipe that falls towards the soil stack. In many apartment blocks the bathroom sits on a concrete slab with only a thin screed on top, and the existing waste runs at a level that suited a bath but not a flush shower. Cutting into the structural slab is not an option.

The alternatives are raising the whole bathroom floor or accepting a low tray. Both can look good; neither is a failure. What matters is that the shower drains properly. A flush floor with an inadequate fall is worse than a slightly raised tray that works.

When raising the floor creates a problem at the door

If the bathroom floor has to rise to make room for the waste, a step appears at the doorway. For some households that is acceptable. For anyone with limited mobility, the reason for wanting a level shower in the first place, a step at the door defeats the purpose. A low tray with a minimal lip may be safer overall. The door may also need trimming or replacing if the floor rises.

When the room is too short for an open screen

A walk-in shower with a single fixed glass panel relies on length: the spray has to stay within the shower area without a door. In a short bathroom, the open side ends up close to the shower head and water reaches the rest of the floor. A shower with a door, a second panel or a slightly raised threshold keeps the room dry. The layout guide helps judge the space.

When the household needs a bath

Families with young children often find a bath easier for bathing them. If the property has only one bathroom and it is a family home, replacing the bath with a walk-in shower may be a decision you regret. Where there are two bathrooms, converting one and keeping the other is often the best compromise. See bath or shower.

When the property is a heavily used rental

Walk-in showers are easy to clean and guests like them. But in a property with very frequent changeovers and little supervision, an open walk-in shower can lead to water on the floor if guests direct the hand shower outward. A screen with a door, or a careful choice of drain position and screen length, reduces the risk. This is a design question rather than a reason to avoid them entirely.

When the walls or structure are not ready

A walk-in shower puts more water on more of the room than a bath with a curtain. If the walls are damp from another cause, if there are signs of structural movement or if the floor below shows old leaks, those must be resolved first. Building a beautiful shower over an unresolved problem only hides it for a while.

If a walk-in shower is not right for your bathroom, a well-built bath-to-shower conversion with a low tray is often the answer. If it is right, our walk-in shower page explains how we build them.

Why do we say this before quoting?

Because a walk-in shower that does not suit the room is the kind of job that comes back as a complaint, and we would rather lose a fashionable design than build something that leaks or floods the floor. Owners appreciate knowing the limits before they fall in love with a photo.

What do we recommend instead?

It depends on the reason. For a shallow floor, an ultra-low tray over a properly renewed waste. For a short room, a shower with a hinged or sliding door. For a family bathroom, keeping the bath and improving the shower over it with a fixed screen. For a busy rental, a slightly longer screen and a drain positioned so water runs away from the open side. Each of these still includes a full waterproofing stage, which matters more than whether the floor is perfectly flush.
