I am remodeling my bathroom and I have taken out a 5' built-in cast iron tub and want to replace it with a freestanding clawfoot tub. I want a 6'0" clawfoot tub. My questions are:

1. I am on a slab and I do not want to break out any more concrete. Can I divert my drain w/o using an overflow valve as long as I have the proper slope to the sewer drain?
2. Do I need a overflow valve and if I do not have one will it drain slower?
3. Can I angle my plumbing supply at a 90 degree angle to come in at the side of the tub?

I am not putting in a shower, just a tub.

Thanks in advance.

1. I am on a slab and I do not want to break out any more concrete. Can I divert my drain w/o using an overflow valve as long as I have the proper slope to the sewer drain? I don't understand the question. Divert your drain to where? By "overflow valve" do you mean a tubwaste and overflow? Your claw foot doesn't have one?

2. Do I need a overflow valve and if I do not have one will it drain slower? You shouldn't have a problem if the old tub is vented either with a dedicated vent or a wet vent. A unvented tub will seek to vent through the overflow. If there is no vent or overflow then you will have a drainage problem.

3. Can I angle my plumbing supply at a 90 degree angle to come in at the side of the tub? If you're asking about the mixing valve the answer's yes you can.
Good luck, Tom
