Best Practice for product titles with dimensions

I am having a debate with someone about the best way to name products on an eCommerce site that has several different dimensions. For example:

1. Epic 13 (33" x 50" x 78") Shower Stall with Center Drain
2. Epic 13 33" x 50" x 78" Shower Stall with Center Drain
3. Epic 13 Shower Stall with Center Drain 33" x 50" x 78"
4. Epic 13 Shower Stall with Center Drain (33" x 50" x 78")

So Epic 13 is the product name, some product names will have the numbers and some will be something basic like Awesome SD without any numbers.

I personally like number 1 the best. My reasons are that the product name is always first, the dimensions come second and are enclosed in parentheses to make them stand out because they are important to the consumer. The drain location is also very important.

The person I am debating with thinks number 3 is the best because they feel it is cleaner looking and it is short because there are no parentheses.

I would like to hear what other people think about this, maybe some suggestions or alternatives. Ideally if there was a study done on this that I can reference that would be ideal. Google did not bear fruit in my quest for the answer.
