Questions about 5×6 half baths
Is 5×6 big enough for a half bath?
Yes. Plan A, Plan B, Plan C, Plan D fit a toilet and a sink with the code minimums: the toilet centerline 15″ from walls and fixtures, and 21″ of clear floor in front of the toilet and the sink.
Can the toilet and sink go on the same wall in a 5×6 half bath?
Yes — that's Plan A. Side by side on one wall keeps all the plumbing in a single wet wall, the cheapest option.
What size vanity fits in a 5×6 half bath?
Up to 36″ wide next to the toilet (Plan D shows 36″, 18″ deep). In tighter spots a 18″ × 14″ wall-hung sink saves floor space.
Which door works best in a 5×6 half bath?
An in-swing door works in Plan A, Plan B, Plan C, Plan D. A pocket door works in Plan A, Plan B, Plan D and frees the swing area.
