Mrs Martin,

It sounds like you need to bring in a Designer/Design Build Company to help you out. The things I would need to know to give you a good layout option with storage would amaze you, so a home visit is the only way to go. Prices range on this service, but I can promise you that spending the extra time in prep and planning saves time and money when it's time for the hammers to come out. I would suggest the Find Professionals section. Before signing a contract or even getting an estimate make sure you check in to the companies. I have know more than a few designers have selected hearing when you mention your budget, a good designer isn't going to show you marble floor tile if you only have 10k to spend... etc.

You need to seriously overhaul that bathroom. Come up with a plan and a budget, and then start taking steps to get it done.
