What Should I Look for When Buying a Walk-In Tub?
| Quick answer: Start with the person's actual entry, turning, sitting, standing, and transfer needs. Then compare the exact tub's threshold, door opening and swing, seat dimensions, grab-bar position, slip-resistant surfaces, control reach, fill and drain system, water capacity, plumbing, electrical requirements, delivery path, service access, and warranty. A walk-in door lowers one barrier, but the right model must fit both the user and the bathroom. |
A walk-in tub is a system, not only a tub with a door. The bather, room, water heater, drain, electrical service, and installation conditions all affect daily use.
Use the checklist below before comparing therapy features or finishes.
1. Begin with the person's movement
The most important test is how the user moves through the bathing sequence:
-
Approach the tub.
-
Step across the threshold or transfer through the opening.
-
Close and latch the door.
-
Turn and sit.
-
Reach the faucet, shower wand, and therapy controls.
-
Remain seated while the tub fills and drains.
-
Stand, turn, and exit.
Ask:
-
Can the user lift each foot over the published threshold?
-
Is a walker, cane, wheelchair, or caregiver involved?
-
Can the user turn inside the entry area?
-
Is the seat height comfortable for sitting and standing?
-
Are the support points located where the user naturally reaches?
-
Can the user operate the latch and controls with current hand strength?
-
Could the bathroom support a different transfer-oriented model if mobility changes?
If the user needs substantial transfer assistance, has significant balance limitations, or cannot safely rehearse the movement, involve an occupational therapist or qualified accessibility professional before ordering.
2. Check the threshold and usable door opening
A lower threshold reduces the height the user must step over, but threshold height is only one part of entry.
Record:
-
Published threshold height
-
Clear door-opening width
-
Inward- or outward-swinging door
-
Left- or right-hand hinge
-
Drain orientation
-
Clear floor space in front of the door
-
Distance from entry to seat
-
Location of any grab bar or support point
An inward-swinging door may use less bathroom floor space but occupies room inside the tub as it closes. An outward-swinging door needs clear bathroom space and may support a different transfer path. Neither is universally better.
3. Evaluate the seat, back, and interior space
Exterior length does not tell you how the tub will feel. Review:
-
Seat height
-
Seat width and depth
-
Back angle
-
Footwell dimensions
-
Knee and shoulder clearance
-
Water depth at the seat
-
Location of jets relative to the user
-
Hand-shower reach from the seat
If possible, compare a mock-up or similarly sized chair and footwell. A seat that is too low, too high, too narrow, or too deep can make transfer and standing more difficult.
4. Verify support, footing, and control reach
Look for support features that match the movement sequence:
-
A built-in grab bar positioned for entry, turning, and standing
-
Slip-resistant flooring and seat surfaces
-
A stable seat and backrest
-
Controls reachable from the seated position
-
A hand shower with enough hose length for seated use
-
A door latch the intended user can operate
-
A faucet with clear hot and cold control
-
Temperature-limiting or anti-scald protection where specified
Built-in features do not replace a complete bathroom safety plan. The floor outside the tub, route to the bathroom, lighting, toilet transfer, and caregiver space also matter.
5. Understand fill, soak, drain, and exit time
The door must remain closed while water is above the door opening. That means the user usually sits inside while the tub fills and drains.
Before buying, confirm:
-
Published faucet flow requirements
-
Household water pressure
-
Realistic fill volume with the bather seated
-
Water-heater capacity and recovery rate
-
Drain type and required household drain connection
-
Whether the selected configuration includes a powered fast drain
-
Expected drain performance under the home's actual plumbing conditions
-
Whether a maintenance heater holds bath temperature rather than heating cold water
Do not assume an advertised maximum capacity equals the normal fill volume. Ask the installer to estimate the realistic volume and fill time for the selected model and home.
6. Choose soaking or therapy features intentionally
|
Configuration |
What it adds |
What to verify |
|
Soaker |
Deep seated bathing with fewer powered components |
Fill volume, drain, seat comfort, and whether electrical service is required |
|
Air bath |
Air bubbles through injectors |
Blower requirements, purge or cleaning instructions, noise, and electrical circuit |
|
Whirlpool |
Water jets and pump |
Jet location, pump access, cleaning procedure, heater, and electrical circuit |
|
Combination |
Air and water systems |
Multiple components, controls, service panels, circuits, and maintenance |
Therapy features may improve comfort for some users, but they also add pumps, controls, cleaning steps, electrical requirements, and service needs.
7. Measure the room and delivery path
Measure the complete route from delivery to final position:
-
Exterior doors
-
Hallways
-
Stairs and landings
-
Interior doors
-
Tight turns
-
Bathroom entry
-
Final rotation space
-
Tub packaged dimensions
-
Tub unpackaged dimensions
-
Tub empty weight
Inside the bathroom, record:
-
Finished wall-to-wall space
-
Toilet and vanity clearance
-
Door-swing area
-
Drain centerline and orientation
-
Supply locations
-
Electrical panel capacity and outlet locations
-
Wall, floor, and service-panel access
-
Floor structure and load path
A tub that matches the old alcove length may still require plumbing, electrical, wall, or floor work.
8. Confirm utilities and service requirements
Powered features may require one or more dedicated GFCI-protected circuits. Requirements vary by model and local code.
The installer should confirm:
-
Voltage and amperage
-
Number of circuits
-
GFCI requirements
-
Pump, blower, heater, and fast-drain loads
-
Grounding and bonding instructions
-
Access-panel locations
-
Drain size and routing
-
Faucet supply requirements
-
Local permit and inspection requirements
Never cover a service panel or powered component that the manual says must remain accessible.
9. Read accessibility claims precisely
Some product pages describe a seat as ADA compliant. That is a claim about a stated product feature. It does not automatically mean that every complete private-home installation complies with the 2010 ADA Standards, which address covered facilities and include requirements beyond the tub itself.
For a private home, focus on the individual user's movement, the product's published dimensions, the surrounding room, and professional guidance. Avoid treating the word ADA as a substitute for a person-specific assessment.
10. Compare the ANZZI and MediTub walk-in tub ranges
ANZZI and MediTub are both part of the SWCorp brand portfolio. ANZZI offers walk-in tubs within its broader bath and home-fixture range, while MediTub focuses specifically on walk-in bathtubs for wellness and accessibility.
ANZZI's current walk-in collection includes compact, standard, soaking, air, whirlpool, and combination configurations. MediTub's current walk-in-tub range adds multiple size series, standard and wheelchair-access configurations, inward- and outward-door options on applicable models, and soaker, air, hydro, and dual-therapy systems.
MediTub also provides a central downloads area for its catalog, model schematics, and installation information. These resources are useful for checking the delivery route, finished footprint, door and drain orientation, seat dimensions, plumbing, electrical needs, and service access before a dealer or installer releases the order.
Use the same checklist for both brands. A larger catalog or longer feature list does not determine the right tub. Compare the exact current model, configuration, and documentation against the user and bathroom.

Frequently asked questions
Is the lowest threshold always the best?
Lower can help, but clear opening, door movement, seat position, support points, and the user's transfer pattern are equally important.
Should I choose an inward- or outward-opening door?
Choose the configuration that fits the user's movement and the room. Confirm swing clearance, transfer direction, toilet and vanity location, and emergency access.
Does a walk-in tub need a larger water heater?
It depends on realistic fill volume, desired temperature, heater capacity, recovery rate, and other household demand. Have the installer calculate it.
Is a fast drain essential?
It can reduce the time the user waits before opening the door, but actual performance depends on the selected system and household drain.
Is a walk-in tub always safer than a conventional tub?
No. It reduces the need to step over a conventional tub wall, but door movement, wet surfaces, turning, seating, standing, and individual mobility still matter.
When should I consider a transfer tub or curbless shower?
Consider alternatives when the user cannot safely step, turn, sit, stand, or operate the door independently, or when regular caregiver access is needed. Seek person-specific professional guidance.
