I recently had the pleasure of experiencing the shower glass installation for my BTO toilet. From the initial inquiries about pricing to the completion of the work, the entire process was seamless, even amidst the busy period leading up to Chinese New Year. Wendy, who assisted me throughout, was exceptionally responsive and ensured clarity regarding what to expect. An appointment was promptly scheduled for measurements, and on the day of installation, the technician efficiently completed the task within just 20 minutes. What impressed me most was the minimal dust generated during the process, making cleanup a breeze.
