I am planning a potential master bath remodel for next year. In doing so looking to trash the current 30 year old acrylic free standing, center of the room, shower stall (unique to this home builder) in lieu of a 48 inch x 84 inch walk in shower with little to no shoulder. Wheelchair accessible.

Looking for a 48" x 84", ready to set and use, shower pan. Just set, finish out, add drain and water, use. Everything I can seem to find that large are pans that require tile to be set on top of them. Personally I DO NOT like tile or any other type of stone. If it requires grout, I hate it! I already have plans for the walls, plumbing and all the assorted extras, just need a pan. Preferably acrylic or composite of some type, available in something other than white.

Somebody point me in the right direction. I have googled and searched until my fingers hurt..... Local building supply stores are useless, talked to all of them. Biggest thing they have to offer is 36" x 60".

TIA!
