is this generally a bad practice?

Generally, no, no problem with it. No code against it in the US, anyway. Though I do like to put garage/workshop outlets and lights on separate circuits so you're not left in the dark if a tool trips a breaker.

however, i was told to have bathroom/toilet outlets on a circuit of their own because a blow dryer can use too many amps.

Right, and bathrooms require their own dedicated 20A circuit for outlets. I'm a little fuzzy on the exact requirements for bathrooms, but I do know their circuits can't be shared with anything that isn't in a bathroom.

Bathroom receptacles have to be fed from a 20A circuit using 12ga wire. You may share that circuit with other bathrooms as long as you only have receptacles on the circuit. You may also have everything in one bathroom on the same 20A circuit, but it must feed only that bathroom.

My typical setup: masterbath gets at least one dedicated 20A circuit for the receptacles, more if it's a big bathroom, lights on a separate circuit (15A).

Smaller full baths may share a receptacle circuit if panel space is tight, but prefer individual circuits for each, lights separate (15A)

Half bath gets one circuit for receptacle and lights/vent. .
