This house has impossibly small bathrooms. We want to redo this one to make it feel more spacious - want to keep the tub because it is the only one in the house - The room is 61" (wall with toilet and sink) x 83" (wall with window between tub/shower & toilet. We hate the white tile and would like to do something without tile (no grout please!)....and hopefully won't have to spend $10K..... Thank you for your ideas!
