Careful with this advice. There is a tiny risk of electric shock if you use an outdoor-rated extension cord, a bigger risk if you use an indoor-rated strip, and a pretty big risk if you use indoor without a GFCI outlet.
The safest thing to do is always to get that outlet installed.

Citation needed. There is certainly not a “pretty big risk” of electric shock. Outdoor vs indoor rated cords should have no bearing on safety inside. Also, if the extension cord is wired to an outlet in the bathroom, the bathroom outlet is almost certainly GFCI unless it’s an extremely old house. If it isn’t, that can be fixed for less than $30 as well. The only thing you’d need to be worried about for an extension cord is the power rating, since bidets can consume a decent bit of power… but most don’t really pull a ton (maybe 600W on full tilt), so almost any extension cord should be able to handle that load.
