Put it in and see what happens, worst case scenario is you pop the breaker so you dial the WC down a bit.
That being said I have a rather large home. Pool 2hp pump (propane heat), Spa with electric heat, 4 ton heat pump, dual electric water heaters, (60g and 40g) dual ovens, 50a induction stove top, 2 large refrigerators and a large stand alone freezer, washer, dryer, salt water aquarium, baseboard electric heaters in the basement, garage and outdoor shed. Too many lights to count that are mostly all on every night as I have a smart home configuration controlling them all. (100% led) 2 WC's on a single 60a breaker, load sharing enabled. Have a 200a entrance and never had to reset a main breaker/fuse in 29 years.
Here is the odd thing, have a whole house backup generator which is only rated at 20kw with a 100a main breaker and a whole house 200a automatic transfer switch. Entire house runs fine off of it including pool, spa and AC. We do not start doing laundry when the gen is running or charge the cars however we do not shut off any breakers to accommodate the reduced electrical input to the home, life goes on as normal running the dishwasher watching TV and internet, once again never an issue. I can tell when the heat pump (65a breaker) kicks in as there is a noticeable dimming of the lights during the initial start up which only lasts a couple of seconds at best. We have had several bad thunder storms this year causing outages and the generator has run at least 48hrs in total in the last couple of months, actually ran yesterday from 2pm to 8pm.
Point is, if one were to calculate the theoretical load there is no way my home should function without popping a breaker here and there.
