There is a wide range of options. If you haven't already, you may want to start by browsing Houzz photos to identify the looks you like.

Here is an inspiration photo. A small bathroom we just finished at a beach project. Clean, classic/white. Fairly inexpensive.

When you say 'redo', are you talking cosmetic changes or a complete overhaul? Not sure where you're located but I agree that the plumbing isn't looking good so I'd want to address that first.

i have 4 months left for my delivery. all i need is a cosmetic change .. so that i can facilitate the baby nicely....

I agree the plumbing looks sketchy i wouldn't invest a lot of money of decorative treatments if the pipes burst down the road. I would also look into your water quality it looks like you have a lot of rust stains that indicates high iron in your water which can really be hard on your plumbing and appliances.

CLR is a product to improve the appearance but i would also look into Water softer as well. Stay away from natural products if your water is high iron they will stain fastest.

Congratulations on the baby.
