Walk-in showers and wet rooms

Removing the hob, levelling the floor, running a linear drain and letting the whole room become the shower.

A wet room removes the step, the hob and usually the door. The floor falls gently to a linear drain, one glass panel controls the splash, and the room reads as a single continuous surface. Done well it is the most generous thing you can do to a bathroom without moving a wall.

It is also the job with the least tolerance for sloppy work. Without a hob to contain the water, the membrane and the falls are the only things standing between the shower and the joists. This is not a renovation to award on price alone.

Typical duration: Add roughly one week to a standard bathroom program for the extra screeding and membrane work.

What is included+ + +

What a quote should cover.

01

Hob removal

Cutting out the existing shower base or hob and preparing the substrate for a continuous floor.

02

Floor build-up and falls

Screeding the correct fall to a linear or point drain across the wet zone, sometimes recessing the floor frame.

03

Linear drainage

A channel drain along the wall or at the entry, tiled-in or with a stainless grate.

04

Extended waterproofing

The membrane runs further than in a hobbed shower, often the full floor, and is certified to AS 3740.

05

Frameless glass

A single fixed panel, sized so the splash zone stays where it should.

06

Slip rating

Floor tiles selected for a wet barefoot area rather than for looks alone.

If a quote leaves one of these out, it is not cheaper. It is smaller.

Questions+ + +

Walk-in showers and wet rooms, answered.

01

Will a walk-in shower flood the rest of the bathroom?

+

Not if the falls and the glass are right. The floor should fall only within the wet zone, the drain should sit along the wall or at the entry, and the fixed panel should be long enough to catch the spray. Poorly set falls, not the absence of a hob, is what causes water to travel.

02

Can any bathroom become a wet room?

+

Most can, but timber floors need the joists checked and often a recessed floor frame so the finished level stays flush. On a concrete slab it is usually straightforward. A renovator will tell you on the site visit which situation you are in.

03

Do I need a shower screen at all?

+

In a large room with a long throw from the rose, no. In anything under about 6 square metres, a single fixed panel is worth it. It keeps the vanity and toilet dry without reintroducing a door.

04

Is a linear drain better than a centre waste?

+

For a walk-in, generally yes. A linear drain needs a fall in one direction only, which makes the floor easier to lay flat with large tiles and easier to walk on. A centre waste needs four falls and forces smaller tiles or complex cuts.
