Designing Kitchens and Bathrooms - Tub surround ideas for odd shaped tub area

I am in the process of redoing my bathroom. It is an older house and the tub was installed in the corner of the room, with the angled protrusion of the attic stairs located from the corner of the tub wall halfway across the tub. I know it is a strange place for the tub, but I dont want to move it. I want to put some type of tub surround around the tub, but my options seem to be limited. Currently it is surrounded by that plain white plastic board. Which I want to replace with something more appealing. I dont think I can use a standard tub surround as I would either have to try and bend a piece to fit the diagonal protrusion or cut the piece and try and match it to the protrusion. I am not sure what I could use or do. Any suggestions for this odd problem, would really be very helpful. Thank you

Welcome to the forums! Not seeing your situation, but in general, I would complete a framing cover the walls with concrete backer underlayment (CBU) and install 4 1/4" ceramic tile. It is not difficult and we can help if you get squashed.

Thank you for your response.. I just completed my first venture in removing the plaster walls and sheetrocking the other half of the bathroom (as it was once 2 rooms and that half still had plastered walls). The part where the tub is has sheetrocked walls already, and the stairway protrusion is framed and sheetrocked, although just painted, which peels constantly. Should I remove all the sheetrock around the tub area, and put up the CBU? Also could I use the bigger size stone tiles? Although I know that it would be difficult to initially hold them in place on the protrusion slope. Sorry so many dumb questions, I am just a novice at all of this!!

Questions aren't "dumb", its what you do with the answers that categorized you. If you plan on tiling or rocking the walls in the surround areas, then yes I would remove the sheetrock, since it is not moisture rated and replace it with a vapor barrier and cbu. It will give you a much more stable strata to install your final wall covering. I only mentioned the 4 1/4" tile because the installation is almost bulletproof. By all means, if you desire the larger tiles, let's have at it. We are here to help if you get stuck.
