Most Frequently Asked Questions

Can you install toilets the same day?
Yes, we typically complete toilet installations the same day throughout Redlands, Glendora, Pasadena, Monrovia, and surrounding areas. We stock popular models and can often install your new toilet within hours of removing the old one.
How do I know if my toilet needs repair or replacement?
We typically recommend repairs for newer toilets with specific problems and replacement for toilets over 15 years old, frequent issues, or major cracks. Upgrading to a high efficiency toilet can also save water and money on your utility bills.
What toilet problems do you repair most often?
We commonly fix running toilets, weak flushing, frequent clogs, wobbly toilets, and leaks around the base. Most toilet problems in Fontana and Upland homes are caused by worn flappers, faulty fill valves, or wax ring failures that we can repair quickly.

We install standard height and comfort height toilets, dual flush models, and high efficiency toilets from trusted brands like Kohler, American Standard, and TOTO. We'll help you choose the best toilet for your Corona or Rancho Cucamonga bathroom and budget.
