Put in a pan and make it a stand up shower with glass or tile enclosure.

The "bathroom" actually had a new toilet but the shower was literally a concrete enclosure painted grey.  

Could you tell me about the washer and dryer enclosure .  

I have at least 8 pretty good sized divits in the back of my tailgate and even the bumper. 

Camp out tailgate?

Could you put an ad on the back of your truck or SUV tail gate area?

The inspectors had come to the property back in 2011 and filed a violation for the building out of the basement and the enclosure of the back porch to create extra living room without architects/structure approval/permits, etc. 

A single shower stall with a great glass enclosure will give you more appeal and modern design.

Making lemonade out of lemons is probably one of the best adages I can think of for learning to be creative and solving problems in real estateif there is a problem with a property or dimension issues you dont always have to go to a contractor to solve the problemcontractors have a certain mindsetand are operating on a specific paradaigmhere are some solutions I have done in the past that have really worked and paid dividendsi had an ejector pump in a bathroom and the space was covered by a makeshift door I decided to have a custom cabinet built that functioned as a trash receptacle and had shelves as well now the unsightly space is home to a beautiful custom cabinet that can be easily removed for servicing the pump when it needs it problem two I bought a house that had front of the shower enclosure removedrather than buy another shower enclosure cost 500.ooi opted to replace the front wall with backer board and tile the front and ended up with a beautiful custom look cost was cheaper than replacing shower enclosure and the look is twice as good problem threewhen i bought my house there was a hole knocked out one of the walls about the size of a  door i suppose thieves came in from the crawl space into this part of the house when it was vacantrather than close in the spacei enlarged the crawls space door poured a concrete floor and created a second exterior doorway to the space making the downstairs ready to become a legal apartment.
