How Fast Does A Walk-In Tubs Drain (And Top 3 Fastest Draining Tubs)

After enjoying a bath in a walk-in tub, we can’t just open the tub door. These safety tubs are special; a senior has to wait for the walk-in bathtub to drain.

How fast does a walk-in tub drain?

It can take up to more than 10 minutes for all the water to go out of the tub. The fastest draining walk-in tubs, however, can be completely emptied in under 120 seconds.

We’ll give you an example of a fast-draining accessible tub further on; however, keep in mind that how fast does a walk-in tub drain depend on 4 factors:

  1. The capacity of the walk-in tub.
  2. Water pressure in your pipes.
  3. The width of your water pipes (3/4 inch pipes are preferable to 1/2 inch ones).
  4. Does the walk-in bathtub have specially designed water pumps to pump out water? (Only the fastest draining walk-in bathtubs include those)

Normal piping and a standard walk-in tub capacity of 60 gallons should drain the bathtub in about 5-10 minutes.

Walk-In Tub Draining Times

Depending on how quickly does the walk-in bathtub empty (or in other words – how long you have to wait in the safe step tub to be able to open the bathtub door), we can put accessible tubs in 4 categories.

Later on, we’ll give you 3 examples of the fastest draining tubs (under 2 minutes).

Here are the 4 rough draining times for walk-in bathtubs:

  1. Super Fast Draining1-2 minutes. Bathtub comes with 2 draining holes/pipes and possibly a drain pump system.
  2. Fast Draining2-6 minutes. Has 2 draining pipes but no drain pump system. Usually smaller tubs below with 50-gallon capacity or less.
  3. Average Draining time6-10 minutes. Only has 2 two inch draining pipe. This is the standard draining time of walk-in tubs.
  4. Slow Draining10-15 minutes. Only for very large walk-in tubs like the barometric tub and if you have low water pressure in the piping.

These estimates of how much time it takes for a tub to empty are exactly that: estimates.

Every walk-in tub has it’s own particular drainage time that is usually specified in its description.

If you would like for a walk-in bathtub to have a fast draining system, look for the ones with 2 draining pipes and a full drain pump system.
