Important Notes Before You Start

Lay out all parts on a clean, flat surface and check them against the parts list before you begin.
Do not use the chair until all assembly steps are fully complete and all bolts are firmly tightened.
Do not confuse the long bolts (A) and short bolts (B), they look similar, so check carefully before inserting.
Hand-tighten every bolt first, then go back and tighten fully with the Allen key once all parts in that step are aligned.
When adjusting leg height, always set all four legs to the same hole position.
Keep all small hardware away from young children.

FAQs

1. Can I use this chair as a regular shower or bath seat without the commode potty installed?

Yes. Remove the commode potty (⑧) completely and clip the seat board cover (⑥) over the opening. The chair then functions as a standard padded shower seat. The aluminium frame and plastic components are water-resistant, but always inspect foot caps before use on wet floors.

2. What is the maximum weight capacity of this chair?

The HOMCOM 3-in-1 Shower Chair has a maximum weight capacity of 299 lbs (approximately 136 kg). Do not exceed this limit to ensure the frame and joints remain stable and safe during use.

3. Is this chair suitable for use over a standard toilet?

The chair is a freestanding commode, not designed to sit over or attach to a toilet bowl. It is intended for use with the commode potty (⑧) included in the box, or as a standalone bathroom transfer chair away from the toilet.

4. How should the chair be stored when not in use?

Store it indoors in a dry, ventilated area away from direct heat sources. Avoid leaving it in humid rooms such as a bathroom long-term, as standing moisture around the frame joints can cause gradual corrosion. Wipe the frame dry before storage if it has been used in a wet environment.
