Hello - We are currently redoing our MB shower but the guest bathroom shower/tub combo is immediately next! After researching it looks like an acrylic tub is overall best but I don't want the non-skid bottom. Can anyone recommend a 30x60 tub, 14" high, nice glossy acrylic without a non-skid bottom? I don't want it to feel or sound flimsy either. Like to keep it below $400. Thanks!
