Quick verdict
When you're prepping a shower or bathroom floor for tile, the waterproofing membrane has to block water and vapor while giving you enough material to wrap walls, floors, and wet areas. These two orange rolls are close in coverage and construction, so your choice comes down to how much weight you put on the title and identifiers attached to each one. The Shower 20 Mil version makes its thickness obvious in the product name and includes a GTIN. The Waterproofing Membrane for Shower roll offers model-name and model-number details instead. If quick title clarity matters most, pick the 20 Mil version; if model identifiers matter more, pick the other one.

Product notes
Waterproofing Membrane for Shower 3.3 ft x 33 ft Roll
This orange roll is built as a 20 mil waterproof and vapor barrier with a reinforced polyethylene core and dual non-woven fabric layers. Its included component is the shower waterproof membrane itself. The product details show a model name, model number, and a box count of one, which gives you a clear set of identifiers before you start a bathroom renovation. The limitation is that the title doesn't call out the 20 Mil thickness, so you need to refer to the product details to confirm what's inside. It still provides the same PE waterproofing underlayment and vapor barrier as the alternative.
Shower 20 Mil Shower Waterproofing Membrane 3.3 Ft X 33 Ft Roll (108 Sq.Ft) - PE
This roll leads with "20 Mil" in the product title, so you know the thickness before reading anything else. It also includes a GTIN, which can be useful if you keep product IDs handy for inventory or reordering. The included component is the shower waterproof membrane, and the product dimensions are listed as 3 x 3 x 40 inches at 5 pounds. The limitation is that the product title is wordier, repeating "Shower" and adding a "- PE" suffix, so it reads less cleanly than the other option. For a straightforward tile-underlayment project, the material and coverage match the other roll, and the title clarity is the primary advantage.
Final choice by use case
If you want your waterproofing roll to state "20 Mil" in the name, include a GTIN, and sit at a lower listed price, the Shower 20 Mil Shower Waterproofing Membrane is the pick. If you'd rather have a roll whose product details list a model name, model number, and number of boxes, the Waterproofing Membrane for Shower gives you that extra identifier context. Both provide 108 sq. ft of orange PE underlayment with a vapor barrier, so the final decision is really about price and identity presentation.
