U have to buy a shower or bathtub. Go by it and click and it says take shower or take
bath.

pres L2 to get onto the menue and go to bye items part go to pluming and bye a bath or
shoer then put it somewhere in your house and make your sim run up to it press X and then
have a bath/shower!!! (if you already have a bath/shower then you don't need to bye one)

you dont know how to take a shower just have a shower and push x and it will let get in
and you take it till your motive goes all the way up as far as it can.

it is easy ,the most helpful thing 2 do is first .......BUY A FRIGGEN SHOWER OR TUB
