How to choose a basin
The basin decides which mixer fits, which trap fits and whether the vanity “stresses”. If you start with the prettiest ceramic, you often end with wrong holes or too short a spout. This guide teaches choosing a basin in sequence. Related: mixer, over/under/inset, trap, plumbing map. Three measurements before the catalogue Width × depth — how much fits the furniture/niche. Mixer holes — 1 hole, 3 holes, no hole (wall mixer). Trap and feed space — under a vanity there is often a “squeeze”. Size examples in the range WidthWhen typicalExample ~400 mmGuest WC, narrow nicheJika Z..

How to choose a toilet
A toilet is the last thing you want to “guess” from a pretty picture. The wrong mounting type means a new frame in the wall, a wrong outlet to the stack or a pan that does not fit the niche. This guide teaches how to choose a WC step by step — then look at concrete models in the inventars.lv range. Renovation basics: plumbing guide. Type comparison: wall-hung or floor. Flush/rimless: flush. Start with mounting, not design Wall-hung or floor-standing? Wall-hung needs an installation frame/cistern in the wall. Floor — often a faster swap in a typical renovation. Where does the drainage g..

How to choose pipes and fittings

Parameters: diameter and pressure. How-to: compression fitting. Three decisions before the metre Material / system — PP-R, PEX, compression, threaded brass/iron.

How to choose a drainage system
Drainage is not a “pretty” choice — it is functional. The wrong diameter or an indoor pipe outdoors ends in smell, blockage or a broken line. This guide sorts drainage choice.

How to choose a water filter for the home

How to choose plumbing for a home renovation
In a home renovation “plumbing” often means four different things on one shopping list: a mixer tap, a basin or WC, a drain and trap chain, and a pipe/fitting line. If you start with the prettiest catalogue photo, you can easily buy the right colour and the wrong connection. This guide teaches you to think in order — then go deeper in each category. The range we use for examples: Plumbing at Inventars (Komforts supply). We skip prices here — they change; sizes, connections and what you will do in the bathroom on a Tuesday evening matter more. Start with the job, not the brand What is be..

How to choose a mixer tap
A mixer tap is where cold and hot water “meet” every day.
