Thinking it through a couple times will make your finished product goal that much more enjoyable. This “wet room / double shower” will have ample wet warm air exhaust and dimmable lighting in both shower and in the soaking tub area. Included is the wiring in the wall for a heated towel rack to keep the towels dry/mold free and warm in the winter. Next step will be to make a custom shower base with a base membrane and mortar tapered to a central drain. This will keep our walls safe from moisture.
