There were several factors that triggered our bathroom renovation. The plumbing was wonky and the tub had worn to a point that it was hard to keep clean. The triggering factor, though, was that the grout on the shower walls had dissolved to a point that the tiles started falling down. (It turned out that there was another layer of tiles behind those. Our house has lots of construction quirks like that.)
Lori's father offered to do it for us. We intended to do it over the winter, but it got delayed til spring: we were slow to order products, then Loews neglected to order one of our pieces, then the tub surround had a slash sawed through it at one edge and had to be sent back. So we didn't start ripping out the old shower until April.
There followed two weeks of inconvenience as we had to go elsewhere to bathe. Lori did most of her bathing at her parents' house; I learned that my office building had a nice locker room with showers. After that, we had the tub and the surround installed, but not the shower doors, so we could take baths but not showers. On May 12, though, the caulk on the shower doors had finished curing, and I got to take a shower at last.
Our new shower is splendidly sumptuous. The showerhead (Amazon link) has two parts, a fixed shower head and a handheld part. The fixed shower head does a great job of covering my back with water luxuriously; the handheld part detaches to focus water on one part for easy rinsing, and adjusts to provide a nice massage as well. (Both parts are independently controllable; when we were in bath-only mode, we would use the handheld part without the fixed shower head.)
I'm also very pleased with the drainage. After years of fighting with a corroded drum trap that was very prone to clogging, our tub now drains so efficiently that water doesn't come halfway up my toes during a long shower.
The cabinetry is not yet done, so I'm not ready to post before-and-after pictures of our bathroom. But showering is lovely. I hope that I'm able to hold on to the delight of this shower for quite a while.
