hi J., i have showered all my kids since they were stable enough to hold themselves up, all before a year old. its easier, safer, and cleaner. they still get bubble baths sometimes, but its mostly showers. just get one of those giant suction cup mats, they have them at bed bath beyond etc. you probably already have the thing that covers the faucet. you can also just lay a big towel on the floor of the tub (if he doesnt move it away), that gives traction too, softens it a little, and even helps clean his feet and "under there" for you, in case he gives you a hard time getting under there long enough to really do the job. i sit in the bathroom with them and play with them or make my phone calls or whatever. they could stay in there forever if i let them. when the baby was first in the shower and just learning to stand, i had to keep a hand on him all the time until he figured it all out, a few weeks, because he would slip at the edges of the mat and try to climb, but he was doing that in the bath anyway, that actually was my signal to cut the baths out! at 17 months, im sure your son is solid on his feet. they love it, and the baby loves being in control of when he is under or out of the water. i have a ton of toys in there, etc. the crayons are awesome. the baby still doesnt like when i wash his hair, he usually fights me, though its getting better, but i just do it quick and then play some more, always end on a good note. they are usually in there so long they are pretty clean before i get to them, especially since they're playing with washcloths and soap anyway and not sitting in a tub of their own dirt! shower with him the first couple of times to transition him in a happy way and show him how it is. try it, you both might love it.
