Since Tiny Living came out and space is at a premium, it would be nice if there were more space saving items. I've mentioned some of this in much older threads but there are a few new ideas.
Over at modthesims, K9DB made two different styles of toilet sink combos, but the toilet and sink have to be placed separately and I know some people don't use CC.
I made some collages of the ideas. There are various styles of toilets with different types of sinks.
There's even a urinal with a sink.
and various other style combos-- there's one with a fold-down sink for an RV
and a washing machine with a sink as well as a toilet inside a shower. I threw in a corner toilets as well.
Then there are some corner sinks
Another suggestion (not pictured): sofa beds, loft beds, bunk beds, and futons. Couches can either have a bed pull out, or can fold down to become a bed or have a bottom drawer slide out with a bed. (I can add pictures later).
Loft beds can come in both single and double sizes and include ladders or stairs. Stairs can be recessed and double as drawers for a dresser or storing items. A dresser, desk, and seating can be placed under the loft bed. My brother used to have a loft bed that had a top bunk, and a lower bed that was perpendicular to the top one. under the bunk there were some shelves sandwiched behind a dresser and a small closet.
Built-in bookcases that fit underneath stairs would also be cool. They could cut in to the walls the way doors and windows do. Same with sets of drawers for dressers or storage. It would be really cool if we could add doors and have small rooms under stairs (like Harry Potter's bedroom).
It would also be nice to have more varieties/styles of combo electronics-- like the TV that plays music etc. It would also be cool (not sure if this exists in game or not) to have something similar to Kindle or an Amazon Fire tablet where books could be loaded and technologically savvy Sims could purchase digital books and read them on the tablet and put the tablet back in their inventory when done instead of having to put books on shelves.
