Kohler vs Fine Fixtures Bathtub
Length and footprint
The Kohler Underscore measures 60 inches in length, offering a longer soaking area for taller users or those who prefer extended immersion. The Fine Fixtures model is 48 inches long, making it a more compact option suitable for smaller bathrooms. If your space allows, the longer Kohler provides more room to stretch out. The shorter Fine Fixtures saves floor space, which is helpful in tight alcoves. You should measure your bathroom carefully to ensure the chosen length fits properly between walls.
Width and dimensions
Width is another key dimension to consider. The Kohler tub is 30 inches wide, while the Fine Fixtures unit is 32 inches wide. A wider tub can feel more spacious and comfortable for your body. The Fine Fixtures offers two extra inches of width, which may enhance comfort during long soaks. However, the Kohler’s narrower width might fit better in alcoves with limited lateral space. Both models are designed for alcove installation, so you need to check your wall spacing. The extra width of the Fine Fixtures could be a deciding factor if you prioritize body space.
Soaking depth
Soaking depth affects how much water is needed to cover your body. The Kohler Underscore has a soaking depth of 19 inches, which retains the same depth as a standard 21-inch bath but with a lower step-over height. This makes it easier to enter and exit. The Fine Fixtures tub has a height of 21 inches, which likely offers a deeper water level for a more immersive soak. Deeper water can be more relaxing but requires more water to fill. You must decide if easier access or deeper immersion is more important for your daily routine.
Drain location
Drain placement affects plumbing compatibility and installation ease. The Kohler Underscore features a left-hand drain, which is fixed in position. This means your existing plumbing must align with the left side of the tub. The Fine Fixtures model also comes in a right-hand drain configuration for the specific variant listed, but variations include left-hand options. If your bathroom plumbing is on the right, the Fine Fixtures right-hand drain fits directly. If it is on the left, you might need the Kohler or a different Fine Fixtures variation. Check your current drain location before buying.
Weight and capacity
Weight impacts floor support needs and handling during installation. The Kohler tub weighs 128 pounds, which is significantly heavier than the Fine Fixtures unit at 44 pounds. The heavier weight of the Kohler often indicates a more robust build or thicker material, providing stability. The Fine Fixtures is much lighter, making it easier to move and install. However, you must ensure your floor can support the filled weight of either tub. The Kohler holds 68 gallons of water, which adds substantial weight when full. The Fine Fixtures capacity is not listed, but its smaller size suggests less water volume.
