Slindsey--a space that is 92 x 133 inches, and not square, will make it difficult to fit a 32" x 60" tub, a 36" sq. min shwr., a w/c and a counter with two vanities plus storage into this space. Dimensions accurate to within .25 cm are critical in this process. Therefore, I suggest working with a design professional in your area. Your budget, whether hiring out the construction, or DIY, involves a significant amount of time & materials. Given the nature of the space, the design will either bless or curse these efforts. Find a Houzz architect(s) in your area, peruse portfolios, and get two blind opinions/fee proposals on how this can be solved. Pick someone you feel comfortable with, and move forward, confident that this professional has first hand knowledge of the existing conditions, which will streamline the design process & create a situation for you to get the best result. Happy Houzzing.
