Check it against my spaceBefore you buy
Four measurements to confirm
- Measure toilet width, tank height, flush control, valve, and supply hose.
- Leave enough room to remove the tank lid and service the fixture.
- Check baseboards, ceiling, nearby doors, vents, and towel bars.
- Follow wall-restraint, leveling, and loading instructions.
Setup reality
Assembly required; secure as directed
Bathroom storage must clear the toilet as an operating fixture, preserve valve and tank access, and use the wall attachment or restraint required by the manufacturer. Follow the manufacturer's instructions and confirm every connection or clearance before purchase.
