Kohler Elevance Rising Wall K-1913-LB (Slide-In) Tub Review

The Kohler Elevance Rising Wall Series stands out for its unique design, which allows the bather to slide into the bathtub. That makes this tub ideal for people in wheelchairs. The K-1913-LB soaking model we evaluated can be upgraded to include hydrotherapy options for those looking for therapeutic and massaging jets.

Design and Style

The Kohler Elevance slide-in bathtub can fill your need for a tub regardless of your level of mobility. Unlike most walk-in tubs, which have narrow doors, this unique tub has a sliding wall built into the side that lowers to the floor. This means you can easily get into this tub without stepping over anything. In fact, you can easily slide over from a wheelchair into the chair-height seat.


Aging in place is easier with this safe-step tub. It's ADA-compliant, which means it includes safety features such as a textured floor to prevent slipping and a built-in grab bar that you can hold for stability. This wheelchair-accessible tub is the same length as a standard bathtub, but because of its sliding door, it's a bit wider, at 34 inches.

The wall is easy to move, requiring only about 5 pounds of force to lift or lower. The door includes two leak-proof seals, so you don't have to worry about water getting on your floor. In case anything happens to those seals, they're protected by a lifetime warranty — as long as you have the tub installed by a qualified professional.

You will spend some time in the tub without water, both while it's filling and while it's emptying as the door must be up and locked during both, so Kohler integrates helpful features into the tub to make those periods go quickly. The waterfall faucet reportedly fills your tub in less than 5 minutes, and the dual-drain system pulls water out of the tub in less than 2 minutes, so you don't have to sit shivering for too long.

Another unique feature of the Kohler Elevance is its shape. Most walk-in tubs have seats that keep you in an upright position. However, this tub is more on an incline, which allows you to stretch out and relax, as you can in a traditional bathtub.


This wheelchair accessible tub costs more than many other safety-oriented soaking tubs, but its convenient design may make it worth the premium for certain circumstances. It includes a 10-year limited warranty for the tub itself, in addition to a one-year warranty on components and the lifetime warranty on the door seals.

The Final Verdict

If you're looking for an innovative design and reputation of a brand like Kohler, the Elevance Rising Wall may be an option. (However, that tub's installation and maintenance could be more complex, based on some user reports we found online.) Just know that wheelchair accessible tubs start at a higher price than others on the market, and additional features increase that cost. However, for some people in wheelchairs or with limited mobility, the unique dropping door may make this Kohler tub worth the cost.
