The same panels, other rooms

Over the toilet, around the tank

The freestanding over-toilet cabinets stand on their own legs and straddle the tank, which makes the tank the thing to measure. Height to the top of the lid, width at the widest point, and the wall behind it for depth.

The rest of them hang on the wall above the tank instead, so the floor stays clear and the question moves to the studs. Either way the printed width on the product page against your tank settles it before the room does.

The vanity with its own light

The makeup vanities carry a mirror with lamps around it, which is the part a bedroom window cannot be relied on for. The drawers underneath take the brushes and the jewelry that otherwise cover the top.

Measure the wall and the chair together. A vanity wants a seat pulled out in front of it, so the floor it needs is deeper than the piece itself.

The entryway bench

The shoe bench does the two things an entryway is actually for. You sit on the leather seat to deal with laces, and the shoes get an address below instead of a pile by the door.

Measure the hallway before it arrives. A bench wants walking room in front of it, roughly a knee and a bag worth, or the front door starts opening into someone every morning.

The gym wall

The tiered storage rack takes the dumbbells, bands and mats that otherwise migrate around the house. It rolls, so the gym can pack itself against the wall between sessions.

Load the heavy things low. A rack, like a dog crate, behaves best when the weight lives near the floor.
