Installing a Tub Surround
Bathroom remodelling presents a unique challenge to DIY enthusiasts because of the temperature and moisture issues. Tile is difficult to install around a tub or shower, especially for the inexperienced. If not done correctly, it could cause a nightmare a few years down the road.
Installing a tub surround is an inexpensive alternative for finishing your bathroom while minimizing future problems. This quick guide gives an overview of such an installation. It is a based on a standard three-panel surround, but you can use the same principles for a five-panel.
Demolition and Surface Prep Unless you're working with new construction or a complete rebuild, you'll more than likely be removing an old surround or ceramic tile first. Removing the old material will almost always cause damage to underlying drywall or plaster. It's best to simply remove everything down to the studs to insure you have a new, even surface to work with.
Use standard drywall to reconstruct your walls. Concrete-based, waterproof board is available, but it's overkill. As long as you install and seal your surround properly, there is little to no danger of moisture damaging the walls. There's no need to finish the drywall, but be sure to at least apply a layer of tape and cover the nails.
Cutting Surround Panels Measure the length and height of the tub's back wall first. The panel's length should not normally need to be cut unless your tub is an abnormal size, but you may have to cut down the height. If so, use a straight edge and cut along the bottom. Centre the back panel so that any gaps on the left and right are equal on both sides. By the way, gaps are normal; they will be covered by the corners.
When you're comfortable with the back panel, do not attach it with adhesive yet. Instead, temporarily tape it in place with masking tape. Mark its position with a pencil so you put it back in the right place later.
