Bathmaster Sonaris

The Bathmaster Sonaris is an economical solution for providing comfort, safety and indepence for the user. In addition, it helps to alleviate lifting in and out of the tub for the caregiver, saving backs!

The Bathmaster Sonaris is operated by a rechargeable battery. It can perform an average of 18 lifts per charge. There is an audible beep and a blinking light to alert you when the battery needs to be recharged. The operator buttons on the hand controller are simple and large to make it easy for anyone to operate. The seat and back snap together for assembly and can easily be separated for storage or transport. The all-plastic design makes cleaning easy, means no rust, and has a complete weight of 26 lbs that can be split into 10 lbs and 16 lbs.

The Bathmaster Sonaris seat back reclines from upright anywhere to 40 degrees of recline. The Bathmaster Sonaris weight capacity is 309 lbs.
There is a 5-year warranty on the seat frame and a 2-year warranty on the hand controller, recharger and optional cover.

The Transfer flaps have to be supported by at least 1" of the tub surface on the transfer flaps. It is ideal to have both flaps supported if the tub/shower is designed that way.


Starting Position --- Fully Reclined Position



The Optional Blue Cover is made from 1/4" closed-cell foam that snaps into place on the seat and the back for extra comfort. You can add it to your Bathmaster Sonaris system by using the drop-down box feature above.
