Low-profile shower trays are ideal for a contemporary look, or for when stepping into a shower becomes difficult. Fitting or installing this type of tray is a straightforward process. Fitting the tray should take less than a day, while the overall job of tray, walls and possibly doors will take longer. These trays range in height from 3 cm (1 1/4 inches) tall to 5.3 (2 1/8 inches) tall. The curb can be made to seem even lower depending on the type of flooring used.
Check to make sure the floor the tray will be sitting on is firm. If there is any flexibility to the floor, add support to the underside of it. A floor that is too flexible can crack a shower tray and cause leaks. Check for level now, also. If the floor needs to be raised, now is the time to do it. If the floor is concrete, use a self-levelling concrete mix to even the floor out.
Clean the floor area and inspect for anything that is sticking up. Any nails, screws or staples need to be either flush with the floor or countersunk, so as not to damage the shower tray. Staples, if they are not actually holding something together, can be removed.
Attach the bottom of the drain assembly to the existing shower drain plumbing. Place the tray into the opening and line up the drain hole with the floor drain. There should be a small gap between the very top edge of the tray and the bottom of the sheetrock wall. The gap will be covered later, with either wall panels that match the tray or tiles, depending on what is chosen.
Install the rest of the drain assembly. Seal the drain with silicone, as it will perform better than a plumber's putty that can dry out and eventually cause leaks.
Seal the tray to the flooring with a colour matching silicone. This will keep water out, ensuring a longer life for the subfloor, tray and regular flooring.
