Set into the floor, not onto it.

The pan sits below finished floor level.

With the waste leaving beneath it.

So the floor is built around the fixture.

It is a construction item.

Not to a finished floor.

The depth and the waste route.

Are both in the floor construction.

Replacing one is a floor job.

Rather than a plumbing one.

The depth between finish and slab.

The pan and its outlet need that space.

Same constraint as a wet room drain.

And for the same reason.

Establish it before specifying.

It is part of the fixture, effectively.

Water reaches it in normal use.

So it needs falls to a drain.

Genuine wet slip resistance.

And tanking as a wet area.

A wet floor with nowhere to drain.

Which is a slip hazard.

And soaks into the construction.

An ordinary bathroom floor is not enough.

Treat the area as a wet room.

Several, by what is available.

Integral or high-level cistern.

A direct flush valve, or manual pour.

The supply decides, not preference.

Which is why markets differ.

Commonly, and for good reason.

Rising from a squat is the hard part.

Particularly for older users.

A vertical rail beside it helps most.

Plan the position with the pan.
