Japanese people shower first, then take a bath. The bath water remains clean and can be reheated for the next time. They also have these unibody whole-bathroom units, no joints, no edges, no silicon, just one continuous smooth surface super easy to clean. In my opinion, they have the best bathing system.
The last time I ever took a bath, I was a toddler, so I’m biased towards showers I’d like to try and soak in a tub once (after showering myself clean like the Japanese do) to know what it feels like.
Worked in construction for a while and hell or high water got the work done. Come home soaking wet or a sheet of ice all over. A bath helped to restore the lost heat and slumber was deep.
When I renovated my bathroom, just so conveniently a 6’ acrylic unit fitted between the walls. Although seldom used now (bathwise), I enjoy the extra space (36” versus 30”) in showering.
Behavioural conditioning: having an active weekday lifestyle I wouldn’t think to soak in the tub much; on a bleak and rainy Sunday, I may decompress with some music, a headrest, and of course some aromatic bubbly…
When I built my house, I bought a stock house plan. It called for a tub in the master bath. Instead I bought a fiberglass base and surround the size of a traditional tub. Low threshold and roomy. Love it. The tub in the full bath gets used to bath the grandchildren or my wife’s plants.
