Window in a tub/shower unit
We’re redoing our second floor and have now come to the bathroom. The house is a Cape Cod style and there was a small addition added to the second floor to allow for a bathroom likely in the 80s. Suffice it to say it is cramped, so there’s not a lot of wiggle room for design. Previously it had a shower unit in one corner, and a window overlooking the back across. We’re looking to add a 54″ tub/shower unit and unfortunately the only space is underneath the window. I know this is not an ideal location.
I’m down to the studs and just about to start installing the insulation, and I was wondering if anyone had any advice on how to keep this absolutely water tight. The plan is 4″ of dense blown cellulose, a vapor barrier, and Prova board for the tile. Beyond the standard sealing I was wondering if there’s any additional products/ techniques I should look into before I install everything and realise I made a big mistake.
I’m happy to provide pictures if it helps.
