went to lowes to find a faucet for a stall shower and really didnt see any faucets that were for shower only. so i purchased one for shower/tub combo. my question is... can i just put a 1/2 male adpt in and cap it for the part going to the tub spout? shower is activated by pulling up the diverter in the tub spout. Im having to have it installed by a pro as Im at moms house with no tools, i dont want the plumber to raise his eyebrows and do an eyeroll as if to say (another dumbass homeowner) what would you do? plumber is coming tomorrow so i need to know what yall think thanks in advance
