The seat belt harness attaches to the tub with a square bracket that has four screw holes. The bracket is screwed to the back of the tub behind the bather, at a position the team marks out for your model on a measurement picture. Once the four holes are marked, you pre-drill small pilot holes and drive the mounting screws. The bracket is fastened from inside the tub, so the belt can be added after installation without moving the tub. A contractor or a handy family member can do the job with a drill and a screwdriver.

Before You Start

Open a ticket at ellasbubbles.com/support or call (800) 480-6850 with your model and serial number and ask for the seat belt mounting measurements. The team sends a picture showing where the bracket sits on your tub so the belt lands correctly on the bather. If you are still deciding whether the harness suits your situation, read about the seat belt option first.

Have these on hand:

• The harness and the square four-hole bracket.
• Four mounting screws. If none came with your harness, the team can send the screws the factory uses.
• A drill with a 7/64 inch bit, which is what the factory uses. A 1/8 inch bit also works.
• A Phillips screwdriver, a marker or masking tape, and a tape measure.

If your harness arrived without screws, ask the team to send a set before you begin. If you would rather buy screws locally, ask the team to confirm the size and type first so the bracket is held the way the factory intends.

Mounting the Bracket Step by Step

1. Transfer the measurements from the team's picture onto the back of the tub with a marker or a small piece of masking tape.
2. Hold the square four-hole bracket in the marked position and mark all four screw holes through the bracket.
3. Pre-drill each hole with a 7/64 inch bit. Do not go larger than 1/8 inch. A hole that is too large gives the screw threads nothing to bite into.
4. Set the bracket over the pilot holes and drive the four screws until the bracket sits snug against the tub wall.
5. Clip the harness to the bracket, seat the bather, and adjust the strap for a comfortable, secure fit.

Why the Pilot Hole Size Matters

The screws thread directly into the tub wall, so the pilot hole does most of the work. A 7/64 inch hole lets the screw cut clean threads and hold firmly. Anything above 1/8 inch weakens the grip, and there is no easy way to recover a hole that was drilled too big. Take a moment to check the bit before drilling.

Other Accessories

If you are outfitting the tub with a bench, shelf or curtain rod at the same time, the accessory installation guide covers those pieces. The seat belt bracket fastens directly to the inside of the tub shell, which is why the team supplies the exact measurements for it.
