As often recommended, you can make the ledge of your enclosure as wide as you want. To extend your ledge on both sides, construct a second frame a few inches longer than the first and then install it parallel to the first frame. If in case you want your ledge to be wider than 16 inches, then build a third frame. Proceed by anchoring these additional extensions to the wall and floor parallel to the previously installed frames.

How to cover the frame? Simply attach ½ inch CDX plywood to the sides and tops of the frame with nails. There is also an alternative for that. Just use a moisture resistant wallboard. Also, use a caulk to seal all of the joints between the bathtub and the covered frame. Coat the wallboard or plywood with moisture resistant primer in order to seal it. And, let the primer dry completely.

You can cover the plywood or wallboard with a tile, wood or any finishing material once it is dry. Then, seal the finishing material well with tile grout, and proceed by caulking all the joints to prevent water damage.

Once the tile or finishing material has been caulked and dried, you can apply a layer of caulk around the bathtub. Simply line all the edges of the tub with masking tape to make a straight line with the caulk. Then, apply the caulk to the edges of the tub and smooth it with your finger. Let it dry thoroughly and remove the tape.

That’s simply it! So, good luck with your bathroom installation project.
