My Buying Guides on Kohler Model 703
When I decided to purchase the Kohler Model 703, I wanted to make sure I understood all the important aspects to get the best value and functionality for my needs. Here’s my detailed buying guide based on my experience and research.
Understanding What the Kohler Model 703 Is
First, I looked into what exactly the Kohler Model 703 offers. This model is a popular pressure-assisted toilet known for its powerful flush performance and water efficiency. It’s designed to handle heavy-duty use while conserving water, which was important for me.
Key Features I Focused On
- Flush Technology: The Model 703 uses Kohler’s pressure-assisted flushing system, which provides a strong, effective flush that helps prevent clogs.
- Water Efficiency: It uses about 1.28 gallons per flush, which meets EPA WaterSense standards—something I was keen on to reduce my water bills.
- Durability: I read that the Model 703 is made with high-quality vitreous china and has a robust build that can last for years.
- Design: The toilet has a classic look that fits well in most bathrooms. I liked its elongated bowl option for added comfort.
Considerations Before Buying
- Noise Level: Since it’s a pressure-assisted model, it’s louder than gravity-fed toilets. For me, this wasn’t a dealbreaker, but I recommend testing the noise level if possible.
- Installation: The Model 703 requires professional installation to ensure the pressure tank is set up correctly. I arranged for a plumber to handle this, which added to the cost but saved me headaches.
- Size and Space: I measured my bathroom space carefully. The Model 703 has a standard height, but you want to be sure it fits comfortably in your layout.
- Maintenance: Pressure-assisted toilets can require more maintenance than standard ones. I read up on routine care to keep it functioning smoothly.
Where to Buy and Pricing Tips
I found the Model 703 available at major home improvement stores and online retailers. Prices vary, so I recommend comparing deals and looking for promotions. Also, consider the cost of installation when budgeting. Sometimes, buying from a store that offers installation services can be more convenient.
My Final Thoughts
Overall, the Kohler Model 703 is a solid choice if you want a powerful, water-efficient toilet. It’s especially great for households that need strong flushing performance. Just keep in mind the noise and installation factors. After getting mine installed, I’ve been happy with its performance and water savings.
I hope my buying guide helps you make an informed decision about the Kohler Model 703!
