Tips & Tricks: No one will tell you!!

What are the services we want from a toilet? It should be clean and hygienic. Sanitation and hygiene performance are prerequisite of a standard toilet. The toilet seat should be designed in such a way that it will not only give pleasure and comfort of sitting but also ensures easy cleaning and stain free surface after every wash.

Bowl cleaning has two parts. First, flush power and second bowl surface. Flush power is the most important feature of premium quality toilet. Flush should be cyclonic discharge type. A good quality toilet should clean up whole dirt in just one flush along with all debris and residues. If you are looking for a budget toilet, then you can go for single cyclonic flush toilet with Vitreous, China or Ceramic core material toilet.

Another considerable point is GPF. Higher GPF is considered to be good but not for me. We should save water by all means. GPF around 1.6 is well capable of flush out dirt efficiently if cyclone system flush is used.

Furthermore, the bowl surface needs to be designed in such a way that can inhibit accumulation of dirt, mold and pathogenic bacteria onto the surface. Height of the toilet is a relative matter. You should choose according your own height and preference. Lastly, for kids, pregnant woman and elderly people it’s better to choose toilet with warm seat and hot air dryer. For comfort and luxury, there is no alternative of self-cleaning toilets with warm seat and hot air dryer.
