Good morning,
we had a meeting with the construction managers yesterday and now have the following consideration:
1.) We organize the complete ceramics (bathtub, shower tray, washbasin, toilet) + fittings ourselves (brand products) and have them installed by a company we hire ourselves. The standard products will be fully credited to us. The builder would then provide the warranty up to the connections. The executing company will only guarantee the work performed and of course not the products we purchased. The advantage would be that with this option we are likely the cheapest and can plan our bathroom (+ guest WC on the ground floor) as individually as we want (see proposal from jochen104). The shower tray and bathtub would have to be installed first and then tiled afterwards.
2.) We take the bathtub (however, the corner bathtub solution would not be possible -> too expensive, only the 180x80 cm) and the shower tray (100x100) from the bathroom exhibition and have them installed by the builder. The remaining items such as washbasins, toilets and fittings we would keep as the "standard" from the builder – but would not have them installed and instead install our desired equipment ourselves afterwards. This way one would have full warranty for bathtub & shower. The remaining standard products could be partly sold and partly set aside for the later expansion of the bathroom in the attic (only a preparation is planned).
Best regards
Gatho
