Building Walls around bath tub

Andiek

We are currently in the the process of renovating the bathroom of a cabin we recently bought. The area that needed immediate attention were the walls around the tub. We tore off the old plastic tub surround and removed the drywall. With the studs exposed we've been slowly but surely rebuilding with cement board, our final goal to tile. Because the devil is always in the details , here's where we're stuck: How far down over the lip of the tub should the cement board come? Should we bring the board all the way down so it rests on the rim of the tub itself, or stop an inch or so above? My dear hubby and I are have two different schools of thought, so we thought we'd turn to the experts!

Many thanks in advance!

Although the board does not have to get all the way down till it touches the finished top of the tub (where you might set your shampoo bottles), it really should get down past the upper limit of the upturned tub lip flange.

Since very few tubs fit perfectly against the studs to allow for such a nice fit, you can bevel the backs of the boards where necessary to get the depth you need.
