Save for the flesh pink towel, I think this tub shower combo is stunning. Simple use of materials, maximizes area, clean lines and an unexpected approach. Perhaps a slight angle on the tub rear wall may be more comfortable and I would prefer the tub in slabs to avoid the grout lines there, but otherwise this is lovely.
Also a very economical approach. A contemporary soaker tub starts at $1500, a porcelain tile like used here could start at $200!
