Our company has the words walk-in baths in the name, so it is worth saying plainly: for roughly seven out of ten households that call us, a curbless shower is the better answer. The tub wins in specific circumstances, and those circumstances are worth understanding rather than guessing at.
The step-over is smaller, not gone
A standard alcove tub asks you to lift a foot 15 to 17 in. A walk-in tub reduces that to a 3 to 7 in sill at the inward-swinging door. That is a genuine and large improvement, and for someone who can reliably lift a foot four inches while holding a bar, it is enough.
A curbless shower removes the lift entirely. Zero inches. On a day when the hip is bad, or after a bout of vertigo, the difference between four inches and zero is the difference between a shower and a sponge bath.
The waiting is the part nobody mentions in the showroom
You sit down in a walk-in tub before it fills, and you stay seated until it drains. With a typical residential supply that is four to eight minutes of sitting in an empty tub getting cold, then eighty to a hundred and forty seconds afterwards waiting for a pair of two-inch fast-drain valves to empty it. Single-valve tubs are considerably slower.
For a daily therapeutic soak that trade is entirely reasonable. For someone who simply wants to be clean and warm in six minutes, it is a poor deal.
Your water heater probably cannot fill it
A walk-in tub holds 40 to 70 gallons. A 40 gallon tank heater delivers roughly 28 to 30 gallons of genuinely hot water before it starts running cool, because cold makeup water dilutes the tank as it draws down.
This is the single most common omission we see in competitor quotes. If your house has a 40 gallon tank, a walk-in tub needs a heater upgrade to 50 to 80 gallons, or a tankless unit confirmed to deliver 5 gpm at a 60 degree rise. That is $1,400 to $2,900 of work that has to be in the number before you sign anything.
When we recommend the tub
- A warm full-body soak measurably relieves arthritis, fibromyalgia or muscle spasm, and that relief is part of the daily routine.
- The person can reliably lift a foot four inches while holding a support, on their worst day and not just their best.
- Bathing is independent, with nobody needing to reach in to help.
- The water heater is already 50 gallons or more, or the upgrade is in the budget.
- The bathroom floor genuinely cannot be recessed, which is rare but does happen over certain post-tension slabs.
When we recommend the shower
- A wheelchair, rollator or shower chair is part of daily life, now or plausibly within five years.
- Anyone else helps with bathing, or might.
- Balance is variable rather than consistently good.
- The household wants the bathroom to read as a design choice rather than as equipment.
- Resale within ten years is a live consideration.
