Uh. my bath tub is stopped up.?

the water is draining really slowly and my other shower is getting water rising in it. could it be something that i flushed? will drian-o-max work? shoud i have to keep plunging?Uh. my bath tub is stopped up.?
cover the shower drain with something that will seal it like a wet towel and some weight, then plunge like hell on the bathtub one. also before plunging try pouring some shampoo down the drain and let it work in for awhile. this works more than half the time on a stopped up toilet without even using a plunger.Uh. my bath tub is stopped up.?
Yep, plunge the heck out of it. Best way is to slowly push the plunger down then briskly pull it up. Do that a few times and be prepared to find a hair clog the size of a chihuahua dog. Gets rather gross pulling it out but you gotta do it if you want the drain to work.
Drano it like 20 times. Works like a charm. Thats what i do.
