FerdY and GDFStudio Tub Comparison
Tub type
The FerdY Koh Samui is a freestanding soaking bathtub. Its design stands alone in your bathroom, allowing you to place it in open spaces. The GDFStudio model is a corner whirlpool tub. Its triangular shape fits into corners to save floor space. This means the FerdY requires more open room, while the GDFStudio is better for smaller layouts. The GDFStudio also includes a hydrotherapy system with jets, whereas the FerdY is a standard soaking tub without jets. You choose based on whether you want quiet soaking or active massage.
Soaking depth
Soaking depth determines how much of your body is submerged. The FerdY Koh Samui has a soaking depth of 14 inches. The GDFStudio corner tub offers a slightly deeper soak at 15 inches. This extra inch in the GDFStudio might provide more coverage for taller users. However, both depths are substantial enough for a relaxing immersion. The FerdY’s 14-inch depth is still considered deep for a standard acrylic tub. You get a solid soak with either option, though the GDFStudio edges out slightly in pure water coverage.
Material build
The FerdY tub is made from 100% glossy white acrylic reinforced with fiberglass. This combination provides durability and a high-gloss finish that resists household chemicals. It is also cUPC certified for safety. The GDFStudio tub features an exterior with oceanic blue glass side panels. The interior material is not explicitly stated in the provided data, but it is a milk white finish. The FerdY relies on a well-known acrylic-fiberglass build, while the GDFStudio uses a unique glass exterior. The FerdY’s material is fully specified for long-term durability.
Overall size
Size affects how the tub fits in your bathroom. The FerdY Koh Samui measures 67.8 inches in length and 31.9 inches in width. It is a long, oval-shaped tub. The GDFStudio is a 59-inch by 59-inch square footprint, designed for corners. The FerdY is longer and narrower, requiring a different wall arrangement. The GDFStudio is wider but shorter in length. If you have a long wall, the FerdY fits better. If you have a corner space, the GDFStudio is the practical choice. The FerdY is also lighter at 81.7 pounds compared to the GDFStudio’s 165 pounds.
Drain location
Drain location impacts plumbing installation. The FerdY tub has plastic and brass drainpipes found on the inner sides of the bathtub. It includes plastic drain connectors that can scale up to 32 inches. This allows for flexible plumbing connections. The GDFStudio includes a UPC certified drainer in its accessory package. The specific location of the drain on the GDFStudio is not detailed in the data. The FerdY provides clear information about its drain setup, including connector length. This makes installation planning easier for the FerdY based on the available specs.
