72 Inch vs 65 Inch Bathtub Comparison

Installation style

Edge: Tie

The Swiss Madison Voltaire is an alcove tub, meaning it is designed to fit into a three-wall enclosure with a built-in apron. This streamlined design avoids the need for additional tiling around the front. In contrast, the FerdY Koh Samui is a freestanding soaking bathtub. It stands independently and does not require surrounding walls for support. This allows for greater placement flexibility, though it requires floor space on all sides. You must choose based on whether your bathroom layout supports an alcove setup or has room for a standalone fixture.

Overall length

Edge: Swiss Madison Voltaire 72 Inch Right-Hand Drain

Length is the primary differentiator in this comparison. The Swiss Madison Voltaire measures 71.9 inches in length, providing a longer soaking area for taller users. The FerdY Koh Samui is listed as a 65-inch model, with actual specs showing a length of 67.8 inches. While the Voltaire is nearly seven inches longer, the FerdY still offers substantial length for most adults. If you are over six feet tall, the extra length of the Voltaire may improve comfort. For average heights, both tubs provide adequate room to stretch out.

Soaking depth

Edge: Swiss Madison Voltaire 72 Inch Right-Hand Drain

Soaking depth affects how much water covers your body. The Swiss Madison Voltaire features a soaking depth of 15 inches. This deep profile allows for a more immersive experience, covering more of your torso. The FerdY Koh Samui offers a soaking depth of 14 inches. While slightly shallower, it is still considered a deep soaking tub compared to standard options. The one-inch difference is minor, but the Voltaire provides a bit more submersion. If maximizing water coverage is your priority, the Voltaire holds a slight advantage.

Drain location

Edge: Tie

Drain placement is critical for plumbing alignment. The Swiss Madison Voltaire comes with a right-hand drain configuration. This means the drain is located on the right side when you are facing the apron of the tub. You must ensure your existing plumbing or new installation matches this orientation. The FerdY Koh Samui does not specify a left or right-hand drain in the provided data. Freestanding tubs often have center or specific bottom drains, but the exact orientation is not listed here. You should verify the drain position for the FerdY before purchasing.

Weight and stability

Edge: Tie

Weight impacts floor loading and handling during installation. The Swiss Madison Voltaire weighs 65 pounds. This lighter weight makes it easier to maneuver into an alcove space. The FerdY Koh Samui is heavier, weighing 81.7 pounds. The additional weight comes from its solid acrylic construction and freestanding design. Heavier tubs often feel more stable and less prone to shifting, but they require a floor capable of supporting the load. You should check your bathroom floor’s capacity if you choose the heavier freestanding option.
