KOHLER K-77795-0SG Eir Comfort Height One-Piece Elongated, Dual-Flush, Smart Toilet with Bidet Built In, White with Sunrise Gold Trim

The Kohler 77795-0SG Eir Toilet in White with Sunrise Gold Trim is a sleek and sophisticated option for those looking to upgrade their bathroom. This one-piece intelligent toilet is designed with a compact and streamlined build, making it a space-efficient choice. The elongated bowl design offers added comfort, while the Comfort Height feature makes it easier for most adults to sit down and stand up, mimicking the height of a standard chair. This could be particularly beneficial for elderly users or anyone with mobility challenges.

One of its standout features is the dual flush system, which provides you the choice between a 0.8 or 1.0 gallons per flush (gpf), making it a water-efficient choice. The stainless steel wand offers a variety of adjustable features, including spray shape, position, water pressure, temperature, and even pulsating and oscillating functions for a customized cleansing experience. Despite its many features, the toilet weighs 116.8 pounds, making it relatively heavy and potentially challenging to install without professional help.

Aesthetically, the combination of white with Sunrise Gold Trim gives it a modern and luxurious look that can enhance the appearance of your bathroom. However, it's worth noting that the toilet is on the pricier side, which might not fit into everyone's budget. If you're looking for a high-end, feature-rich toilet and are willing to invest more, the Kohler 77795-0SG Eir could be an excellent choice.

Buying Guide for the Best Kohler 10 Inch Rough In Toilets

When choosing a Kohler 10-inch rough-in toilet, it's important to consider several key specifications to ensure you select the best fit for your bathroom. A rough-in measurement is the distance from the wall to the center of the toilet's drainpipe, and a 10-inch rough-in is less common than the standard 12-inch, so it's crucial to get this right. Beyond the rough-in size, other factors like bowl shape, flushing system, and height can significantly impact your comfort and satisfaction with the toilet. Here's a breakdown of the key specs to consider and how to choose the right one for your needs.
Bowl ShapeThe bowl shape of a toilet can be either round or elongated. Round bowls are more compact and are ideal for smaller bathrooms, while elongated bowls offer more comfort due to their larger seating area. If space is limited, a round bowl might be the best choice. However, if you have a larger bathroom and prioritize comfort, an elongated bowl would be more suitable.
Flushing SystemThe flushing system determines how effectively the toilet clears waste. There are gravity-fed and pressure-assisted systems. Gravity-fed systems use the weight of the water to create flushing pressure and are quieter and more common. Pressure-assisted systems use compressed air to forcefully clear the bowl, which is more powerful but noisier. If you prefer a quieter toilet and have standard flushing needs, a gravity-fed system is sufficient. For higher performance and better clog prevention, consider a pressure-assisted system.
Toilet HeightToilet height can affect comfort, especially for taller individuals or those with mobility issues. Standard height toilets are around 15 inches from the floor to the seat, while comfort height (or chair height) toilets are about 17 to 19 inches. Comfort height toilets are easier to sit down on and stand up from, making them a better choice for older adults or anyone with knee or back problems. If you have no specific mobility needs, a standard height toilet may be perfectly adequate.
Water EfficiencyWater efficiency is measured by the gallons per flush (GPF). Modern toilets typically use 1.6 GPF or less, with high-efficiency toilets (HET) using 1.28 GPF or less. Choosing a water-efficient toilet can save you money on your water bill and is better for the environment. If conserving water is a priority for you, look for a toilet with a lower GPF rating. However, ensure that the flushing performance is still effective to avoid multiple flushes.
Design and AestheticsThe design and aesthetics of the toilet can impact the overall look of your bathroom. Consider the color, style, and finish that will best match your bathroom decor. Kohler offers a variety of designs from traditional to modern. Choose a design that complements your bathroom's style and meets your personal preferences. While aesthetics are important, ensure that the design does not compromise functionality.
